FRANK J. B USSMANN, OF NEW YORK, N. Y., ASSIGNOR TO THE INTERSTATEBOTTLE I STOPPER 00., 1110., O f BROOKLYN, NEW YORK, A CORPORATION OFNEW YORK.

To all -whom it may concern: I

Be it known that I, FRANK J. Bussamms,

a citizen of the United States, residing'in the borough of Brooklyn, NewYork city,

in the county of Kings and State of New York, have inventedcertain new.and useful Improvements in Bottle-Seals. of which the following is aspecification.

My invention relates to improvements in crown caps for sealing bottlesand my objects are the production of a cap which will more securelyseal-a bottle with a standard sized lip, efiectually seal bottles whoselips are abnormal with respect to either size or shape and which willpermit the use of thinner tin plate than has hitherto been customary inmaking metal shells for bottle caps.

In the drawing Figure 1 is a sectional view of a complete cap; Fig.2 aview'of a standard bottle lip and Fig. 3 a viewof acrown. on a bottle.

My crown consists of the usual metal shell 1 provided with the dependentflange or skirt 2 which has the inner'corrugations 3 and the outercorrugations t, at its lower part. The sealing gasket. 5 isordinarilyheld inplace by a collet 6 charged with an adhesive medium.

The bottle 7 has a lip 8 adapted to engage the skirt of the crown capand when the cap is brought intosealing relation with the lip the innercorrugations 3 are forced under 7 the greatest diameter of the lip andmain- 1 applied to a bottle itwill securely whether the bottlelip bestandard or ab- I am also enabled tain the cap in sealing position.Hitherto the inner corrugations of the skirts have been formed straightin themetal shells and if the lip on the bottle has been abnormal eitheras .to shape or size thelock has not been secure, and the cap has beenblown off in pasteurizing due to its inability to hold under theinternal pressure due to the expansion of the contents of the bottle.

'My invention so shapes the inner corrugations of the skirt that whenthe calp 0 normal in size orshape. to use thinner tin in making shellsand still obtain the same locking power as has hitherto been obtained bythe use of the thicker 'ihe constructionwhich enablesme to obbelow thegreatest diameter of the bottle lip.

formed on the inner faces of the inner corrugations 3 at a sufiicientdistance below the top of the shell that when the cap is being puton thebottle the top or sealing pressure will bring the inward projections 9slightly \Vhen the side or bending pressure is applied to thecorrugations forcing them in wardly theinward projections will strikeandslide downwardly along. the retreating face 10 of the lip (below theline aa) and draw the metal shell more forcibly intomore intimatecontact with the bottle lip than has heretofore been possible, withoutbreaking the bottle and this even to the ex-. tent of drawing into andperfectly sealing chipped bottles. When in locked position these inwardprojections 9 act as claws and grip the under part of the bottle lipmore firmly and solidly than any straight. skirted cap possibly canthereby permitting the use of thin tin in crown shell'making. i It isobvious that it is not necessary to provide each of the innercorrugations with an in-' ward projectionfso lon as a sufficient numberarepresent to perirm the added lock ing function. The cap is removedfrom the bottles ,by the aid of any of the ordinary openers andrequireddittle or no more exertion to do this than when the ordinary capis removed.
